From Introduction: "The present report describes the condition of all of the porcelain enamels after exposure for 3 yr."

Report discussing earthquake activity in the United States during 1930. The report is broken down by regions and has sections for specific earthquakes.

Tabulated data presenting the results of elemental analyses for stream sediment samples taken from 1017 data collection sites in the state of Louisiana. Results of Oak Ridge National Laboratory's Elemental Determination-Methods and Detection Limits are given in ppm (see page 18 of report).

From introduction: Salt occurs at depths less than 500 feet in six salt domes in Texas and Louisiana. Underground mining operations are being carried out in each of these domes. The following notes have been prepared in an effort to furnish data regarding chemical composition and structure of the rock salt in the shallow deposits.

From Introduction: "In this paper are presented the results obtained to date from the inspections of steel pilings. The investigation will be continued by additional inspections of pilings in other parts if the country in order to cover a wider range of soil environments."

Technical paper issued by the Bureau of Mines over an engineering study of the Cotton Valley oil field. The history, geology, development, and production of the field are discussed. This paper includes tables, maps, photographs, and illustrations.

From abstract: This report is the third in a series of reports describing the regional geohydrology of the northern Louisiana salt-dome basin. The Wilcox-Carrizo and Sparta aquifers are the principal Tertiary aquifers of regional extent in the basin. The Wilcox-Carrizo aquifer is not affected by regional water-level declines, as no large pumping centers have been developed. Water-level fluctuations in wells are mostly seasonal. As shown by the hydrographs of seven wells, the seasonal fluctuations are generally less than 10 feet annually. Therefore, the potentiometric surface of the Wilcox-Carrizo aquifer in northwestern Louisiana is shown by contours using data collected from 1960-80.

From abstract: This report, which describes the hydraulic characteristics of the Wilcox-Carrizo aquifer, is the fourth in a series of reports describing the regional geohydrology of the northern Louisiana salt-dome basin.

Abstract: The model study was conducted to evaluate the characteristics of flow in the inlet channel, original sump, energy dissipator (saxophone outlet), and outlet channel and to develop practical modifications required for improving the hydraulic performance of the structure.

Abstract: The report summarizes progress on geologic and hydrologic research related to the disposal of radioactive wastes. The research is described according to whether it is related most directly to (1) high-level and transuranic wastes; (2) low-level wastes, or (3) uranium mill tailings. Included is research applicable to the identification and geohydrologic characterization of waste-disposal sites, to investigations of specific sites where wastes have been stored, and to studies of regions or environments where waste-disposal sites might be located. A significant part of the activity is concerned with techniques and methods for characterizing disposal sites and studies of geologic and hydrologic processes related to the transport and (or) retention of waste radionuclides.

From introduction: In this study on raw material sources of uranium the Southern Interstate Nuclear Board has catalogued all known occurrences of uranium and some references to thorium in a 17-state area (P1. 1). These occurrences have been evaluated as potential sources of uranium by the State Geological Surveys and the consultant group of SINB. Favorability guides have been applied to the known occurrences and recommendations have been made for future action by the states involved, federal agencies, or by industry. State recommendations are included in state-by-state summaries. The state reports were written either by personnel of the State Geological Surveys or were abstracted from State geological survey data by members of the consultant group...The purpose of this study was to compile information on and systematically assess uranium and other radioactive occurrences in the region. The SINB undertook the project because of its statutory, interstate capability as an extension of government in each of the 17 states, an arrangement that lends itself effectively to this cooperative undertaking.

First report regarding geotechnical field investigations meant to apply current state-of-the-art knowledge and methods to assessing the in situ characteristics of susceptible point bar deposits below Baton Rouge.
